Someone running a longitudinal dose-response study just grabbed the 30mg vials — they're usually the ones who've already burned through 2mg and 5mg sizes, and they know the bigger format saves reconstitution time.
It's a, ≥99% by HPLC, with MS verification — we include teh COA, and the -20°C storage with light protection isn't optional, it's essential for that 24-month shelf life.

Basically, if you're working with water-soluble peptide reconstitution protocols, this works well, but it's not suited for any in vivo models without proper sterile handling — and custom MW formulation means you should check lead time if you need a specific molecular weight.

We usually stock 2mg, 5mg, 10mg, 15mg, 20mg, and 30mg sealed vials, but lead for really large orders is about 20 days or so.
Also, most buyers go with the 10mg vials — it's just easier to aliquot without excessive freeze-thaw cycles.
We don't have a strict MOQ on the 2mg size — you can order as few as 10 vials for testing. For larger quantities, just let us know and we'll work out pricing.
Standard lead time is 7-10 business days after order confirmation. Custom molecular weights might add a couple days for verification, but we'll keep you posted.
Yes, absolutely — every shipment includes the COA and HPLC data. You'll get purity verification and MS confirmation for peace of mind.
We can customize packaging sizes beyond the standard 2mg to 30mg vials. Just tell us what you need, and we'll adjust the vial type and label accordingly.
Keep it at -20°C, protected from light, and sealed in the original vial. Avoid freeze-thaw cycles — once reconstituted, use it promptly and store at 2-8°C.
